n = 1.7 and (A beam of light) θ₀ = 17°.  Calculate θᵣ, the reflected angle.

The speed of light in a particular type of glass is 1.68  108 m/s. What is the index of refraction of the glass?

A ray of light enters a narrow prism along the normal as shown. Calculate the angle (degrees) at which the ray exits the prism, relative to North (i.e. up the page, not the normal to the glass). The index of refraction of the prism is n = 1.54. The angle of the prism is theta = 19.42 deg.

Water has an index of refraction of 1.33. What is the speed of light and water in km/s?

Distances in space are often quoted in units of light years, the distance light travels in one year (365.25 days). How many meters is a light year? Provide the solution: x 1015 m

What would be the speed of light through a particular medium if the frequency is 5.63 x 106 Hz and the wavelength is 63.86 m?  Your answer for this problem will not have any decimal places.

Consider a mirror lying along the x-axis in R2. A laser starts at the point (−2, 6) and is fired in the direction of ⟨4, −3⟩. The beam travels until it hits the mirror, where it reflects off the mirror and then travels until it hits a wall on the line x = 20. (a) Give a parametrization for the initial path of the laser. (b) At what point does this beam hit the mirror? (c) Give a parametrization for the path of the reflected beam. (d) At what point does this beam hit the wall?

ray of light strikes a flat block of glass at an incidence angle of ?1 = 38.6°. The glass is 2.00 cm thick and has an index of refraction that equals ng = 1.52.   a.)What is the angle of refraction, ?2, that describes the light ray after it enters the glass from above? (Enter your answer in degrees to at least 2 decimal places.)   b.) With what angle of incidence, ?3, does the ray approach the interface at the bottom of the glass? (Enter your answer in degrees to at least 2 decimal places.)     c.) With what angle of refraction, ?4, does the ray emerge from the bottom of the glass? (Enter your answer in degrees to at least 1 decimal place.)     d.) The distance d separates the twice-bent ray from the path it would have taken without the glass in the way. What is this distance (in cm)?     e.) At what speed (in m/s) does the light travel within the glass?    f.) How many nanoseconds does the light take to pass through the glass along the angled path shown here?
